how can we generate a vector of length 100 with random number in between 0 and 1 with uniform probability such that sum of these numbers/100 is equal to 0.75

need X vector of length 100 which only contains values in between 0 and 1

like X = [0.8 0.03 0.5 0.8 0.95 .......] such that sum(X)/100 = 0.75
